Fire turret "projectile" from origin to end

Hello guys, i'm trying to do a 3D arkanoid however i'm trying to add a random turret so it shoots some little laser and it should work as intended on the little image down here:

However i'm failing even if I use it with Lerp or MoveTowards, like there's an offset from the target point when it actually shoots this "laser" what's the recommended approach when trying to implement such thing? thanks in advance! not asking for code or anything like that, just wanna hear some ideas on how would I implement this the correct way? truly appreciated!
